Hi
We are using DO kubernetes and trying to implement isolation of pod by network policy

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: "node-isolate"
spec:
  podSelector:
    matchLabels:
      app: myapp
      release: mydep
  policyTypes:
  - Ingress
myapp-6f5c8dbd6d-rql4t                  1/1       Running             0          1d        app=myapp,pod-template-hash=2917486828,release=mydep

But I can access pod from another pods with curl via service name and port,
Is DO use network stack that doesn’t support networkpolicies?
Like flannel?

Hi there, yes, they are using flannel

Hello,

Is it still impossible to apply NetworkPolicy with DigitalOcean K8S clusters?

Edit:
It is apparently supported now. I’ve received a feedback from one of the DOKS engineers who told me that:

Yep we do support the canonical network policies plus the extra ones provided by Cilium (which is our CNI plugin of choice).
